Operation of District Heating Equipment (FSI-FSC)

Academic year 2021/2022
Supervisor: Ing. Petr Kracík, Ph.D.  
Supervising institute: all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The main aim of this course is to get the students acquainted with the energetics in Czech Republic, with the construction and operation of power supply stations (mainly power plants and combined heat and power plants) and their integration to the power and district heating grids.
Learning outcomes and competences:
The students will have basic understanding of the energetics in the Czech Republic and will be able to conceptually design combined heat and power plants.
Prerequisites:
Knowledge of Thermomechanics, Fundamentals of Power Engineering I and II. Heat engines.
Course contents:
The course focuses on power stations (power plants, combined heat and power plants, pure heat plants) in centralised and decentralised configurations. It is followed by lectures on their implementation into the distribution grids, elementary conceptual design process, calculation of heat losses and overall energy consumption.
Teaching methods and criteria:
The course is taught in a form of lectures that have theoretical character containing basic principles of given subject.
The calculation classes will be based around Open Source program OpenModelica. During the semester, video-lectures will be regularly released on University Moodle website. The videos will contain theory to each section and their implementation into the program. There will be individual assignments corresponding to covered topics. At the given scheduled time for the class there will be computer lab available, where individual consultations can take place.
Assesment methods and criteria linked to learning outcomes:
Credit requirements: active participation in the classes. Submission of all assignment in the field of calculations of energy equipment.
Requirements for the exam: written part in the form of questions and examples, oral discussion on a given topic
Controlled participation in lessons:
The presence on lectures is recommended and will be delivered according to the schedule.
Calculation classes: submission of all calculation assignments
